I can relate to this, too.
Kind of like looking at a word that I know is spelled right but the letters are all wrong - except it's the world that looks "wrong". Yeah, it can be very troubling and it's even hard to describe. But things around me don't look real, don't make sense, don't look right. Really weird to look at my BF and not quite recognize him. Or driving or walking and the streets look wrong.

I get it more when I'm stressing, too. And when I'm stressing, I can't shake it off as easily. That's when I need to do non-visual grounding exercises - like touch or taste or music. When my eyes are playing tricks on me, I need to find another sense to get me back to "reality".
You aren't alone with this one!
